To all whom it may concern:

Be it known that I, MlLoN J. TRUMBLE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a Crude-Petroleum and Natural-Gas Separator, of which the following is a specification.

My invention is designed to efl'ect a separation of natural gas from the crude oil when the same is first delivered from the well, and is also'designed to accomplish the cleaning of the oil from free water and sand at the same time.

- My invention is also adapted to overcome the unseating of the pump valve in an oil weli when an excess of natural gas is present with the oil, thereby materially increasing the amount of oil produced from Wells where high pressure of gas exists.

My invention is also adapted to reduce the velocity and equalize the delivery of oil from wells in which the pressure of gas causes the oil to flow in gushes or by heads. My invention is also effective in maintaining the lighter gravity series of the crude oil in combination with the heavier series of the .oil, thereby producing from on wells a product of lighter gravity than where the oil and gas is permitted to separate on exposure to ordinary atmospheric conditions. a

My invention consists in the arrangement and combinations of parts as hereinafter set forth.

The accompanying drawings illustrate my invention and one method of its application:

Figure 1 is an elevation showing my invention as applied to an oil well, the velocity reducing means and gas line being broken to contract the view.

F ig. 2 is a vertical section of the expansion chamber and fragment of velocity reducing means and oil heating means.

Fig. 3 is an inverted section of the expansion chamber taken on the line m w Fig. 3.

Fig. 4 is an enlarged vertical section of oil stopper for gas line.

Fig. 5 is an enlarged view of the oil outlet, the lower end of the outlet pipe and closure therefor bein shown in section.

As shown in the rawings the expansion chamber 1 is provided with a tapering settling chamber 2 which in turn communicates with and is supported by a stand pipe 3. The top 4 of the chamber is centrally perforated and a T 5, having its stem 6 disposed horizontally, is arranged to register with the central perforation in the top 4. Velocity reducing means, such as pipe 7, communicates with the horizontal stem 6 of the T 5 and delivers oil and gas into the interior of the chamber 1 through the vertical member 6 of the T. The velocity reducing means 7, as shown, consists of a pipe many times greater in areaythan the oil pipe 8 which delivers the oil from the well 9. K I

A gas pipe 10 is arranged to lead the gas from the upper end of the T 5, and connects with the gas collector Within the expansion chamber, which will hereafter be explained. A gas pressure regulating valve .11 is provided'in gas pipe 10 and controls the passage of gas from the expansion tchamber to any suitable receiver or destina- Oil outlet means 12 is provided from the chamber at a .point intermediate the settling chamber of the expansion chamber and the oil inlet means. When the character of the oil demands, oil heating means may be provided such as the steam jacket 13 which surrounds the velocity reducer 7. A

steam pipe 14 is arranged to supply steam to such jacket. When desired a pipe 15 takes steam from the jacket 13 and deliversthe same to a coil 16 arranged in the settling chamber 2 to further heat the oil within the chamber. The exhaust from the coil 16 is effected through pipe 17 which passes through. the wall of the chamber.

A pump tube 18 having a sucker. rod 19 is shown mounted on the casing head 20 of a.

well 9. A gas pressure pipe 21 is shown as connecting the gas pipe 10 with the casing head of the well to apply the pressure of the gas within the expansion chamber to the top of the oil within the well 9 which surrounds the pump tube 18. A valve 21 maybe provided in the pressure pipe 21 to regulate the pressure within the well, or such valve may be dispensed with, in which event the pressure on the oil surrounding the pump tube and the oil in the oil pipe 8 will be equalized.

Oil dividing means are provided interior lit) of the expansion chamber, such as cones 22 and. 22* Preferably these'dividingcones are-spaced apart, one below the other, as shown, with their peripheries nearly in contact with the wall of the chamber. The oil is delivered onto the upper surface of the cone and spreads over the same evenly and is. brought'into contact with the wall 23 of the chamber and flows downwardly thereover until it is collected .in the settling chamber... The cone 22 is provided as a supplemental. spreader to insure the even distribution of the oil over thewall of the chamber. As shown in the form herein illustrated,the.cones 22 and 22 are supported inthe upperportion of the expansion chamher by means.- of. gas collecting chamber 21L and pipe 25.: Pipe25 is screwed into flange 26 which in turn is seated upon and closes the-upperendof the vertical member 6 of the Tit), to which issconnected the elbow 27 of the gas pipelO. The lower end of the pipe 25.11; screwedsinto. a reducer 30, ar-

ranged. with its larger end looking downward to receive the upper end of the gas collecting chamber 2% which is open at its lower end 28.- The gas collecting'chamber isalso provided with gas admitting ports 29; :29 'and'29 arranged between the cones 22 and 22" which are protected thereby to prevent. theentiiance of oil into the gas line.

Avalv-e seat 31 is provided in the reducer 30.,anda .valvestopper 32 is provided with means for seating the same when oil may rise within the chamber to a point whereit may gain access. to the gas line 10. As shown thisv stopper 32 comprises a flat circularbody having a beveled edge adapted to. fit the valve seat in the reducer, and is, provided .With a perforated shank 34: throughwhich thev float rod 35, actuated by float-33, passes to open and close a vacuum breakeropening. 36 in the stopper before aetuatingthe stopper 32. A slot 38 is provided in the .shank 3 L which permits of the passage of a pin therethrough and through.

the float rod tolimit the movement of such rod, in breaking the vacuumto permit the unseating of the stoppers The movement of the. stopper, float rod, and.,,float,,. away from the valve seat is limited by the end of shank 34: coming into contact with; a bracket 39. Abracket 40 is arrangealvneae the bottom of the gas col-- lectingchamber to guide the float rod 3,5.

Aitrapped oil outletfrom the-chamber 13 provided which consists of a submerged pipe 41 providedwith a closure 42 which 1s actuated by means of a float t3 which is so adjusted as to cause the pipe .to be closed to the exit of oil before the level of oil reaches the ropen'end. of the pipe,.to thereby prevent the escape of gas alongwith the outflowingoilflfrom the chamber. Other forms of traps will readily suggest themselves, but

incense.

the form herewith disclosed illustrates the function desired to be derived. A valve H is provided to permit sand and water to be drawn from stand pipe and settling chamber when desired.

It is to be remembered that an important feature of my invention is to provide means whereby the oil is divided into a thin or broken body whereby the gas may readily escape from its engagement therewith and it is alsodesirable to maintain'the oil in its divided form for a period of time sutlicient for all the gas to free itself from the oil. It is also desirable to maintain the oil in a quiescent condition for a short period of time within the settling chamber to permit I jacket 13 up to or about thelboiling point of water. This heating will result in weakening the surface tension upon any water contained in the oil and allows the same to settle in the bottom of the chamber. The settling of the water may be materially assisted by the pressure of the gas within the chamber, and, if necessary, more heat may beapplied to the oil by means of the steam coil 16.

In case oil is being taken from a well of the flowing type, and is intermittent in its heads, the velocity reducer will afi'ord means for equalizing the flow of oil into the expansion chamber. In case a large amount of oil should be delivered to the expansionchamber, and the egress. thereof should be slower than the amount coming in, the float 33 will actuate the stopper 3'2 and close they gas outlet to prevent oil from getting into the gas line. The gas pressure will then increase and thereby force the oil from the. chamber until the float will drop down to open the gas line again. The pressure regulating valve 1 1 in the gas line 10 controls the-exit of gas from the expansion chamber and thereby keeps a constant pressure on the oil within the chamber.

In the case of a wet gas, or a gas saturated with an oil of the lighter series. such as gasolcne, it is desirable'to maintain as higher in gravity, according to the Baum as produced by my invention increases the pumping efiiciency and the production of the well, thereby making profitable producers of Wells that have theretofore been unprofitable.

The oil flowing from the expansion chamber through outlet 12 may be conducted to any suitable tank or receptacle either by the pressure of the gas within the chamber or by gravity.

When desired, a safety valve may be provided for the chamber 1 to permit escape of gas from the expansion chamber in the event that valve 32 should'become stuck or' remain seated on its seat. In. some cases the float 33 and valve 32 may be dlspensed with.

It will be noted that the action upon the oil while flowing down the wall of the expansion chamber in a thin film under pressure permits the free, dry, gas to readily escape therefrom, while the pressure exerted upon the oilsurface backed by the wall of the chamber holds the lighter liquids, such as gasolene, in combination with the oil body, and I desire to be understood as pointing out and claiming this action as being of great benefit to the crude oil derived from the well on account of keeping the gasolene series in combinaton with the main body of oil.
